ROAD-BONE.

Specification of Letters Patent. Patented Apr. 1T3, T915.

Application filed February 15, 1913. Serial No. 748,546.

To all whom it may concern Be it known that T, JOHN H. KOLPIEN, a citizen of the United States, residing at Westfield, in the county of Chautauqua and State of New York, have invented new and useful Improvements in Road-Hones, of which the following is a specification.

This invention relates to road hones and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claim.

The object of the invention is to provide a road hone of comparatively light draft and which will to a large extent complete the operation upon the road with a single passing of the hone over it.

Other objects of the invention will appear from the specification and claim.

The invention is illustrated in the accompanying drawings as follows Figure 1 is a plan view of the hone. Fig. 2 a section on the line 22 in Fig. 1. Fig. 3 a section on the line 33 in Fig. 1.

The frame is made up of the front rails 1-1, the rear rails 22 and connecting bars 3. All of these parts are ordinarily formed of angle iron, the bars being riveted or otherwise secured to the rails. Cutting blades 5 are secured to the front rails and cutting blades 6 are secured to the rear rails. Thpse merely give a wearing face to the rar s.

Tt will be observed that the front rails slant to the line of draft so as to carry the material moved by the hone from the center toward the outer ends of the front rails. Tn other words, the front rail is V shaped with the apex toward the front. The rear rail is V shaped with the apex toward the rear and the ends of the rails 2 project slightly beyond the ends of the front rails so that material that is moved past the ends of the front rail is taken up by the rear rail and then moved toward the center. The final result is to move the material first toward the outside to start the leveling operation and then toward the center and the final efi'ect of the device is to move a greater portion of earth toward the center than toward the outside so as to take up the natural movement of wash of the dirt toward the outside and thus maintain the crown of the road. An opening 7 is left between the rear rails 2 so that any accumulation of material by the rails may pass out between them. This material may be smoothed out if it is found necessary in any convenient manner.

Tn order to allow the parts of the hone to more readily follow the contour of the road especially the crown of the road, T prefer to joint the two sides of the frame together. Hinge lugs 8 are secured to the central bars 3 and the hinge rod 9 extends through the lugs and forms a pintle for the hinge. The frames are provided with the centrally located bars 4-4, the upper plates of the angles being set slightly apart. Draft chains 10 are secured to the ends of two of the bars t and unite in a ring 11 to which the traction is applied.

Parts of the road are often found too soft to permit of the action of the scrapers with the full weight of the hone upon them and it is often also desirable to move the hone without having the scrapers operate. To adapt the hone to such contingencies, T provide the runners 12. These have the draft chains 13 which are secured to brackets 14: on the front rails. The runners have the uprights 15 which extend through the slots between the upwardly extending plates of the angle irons 4. These plates thus form guides for the runners. Levers 16 are provided for adjusting theblades relatively to the runners. The levers are secured to the uprights 15 by means of the pins 17 and the levers are pivoted on the posts 18 by the pins 19. The posts 18 are secured to the bars 4, one to each bar allowing a space for the levers between them. l-T ratchet bar 20 is secured to one of the rails & and has the serrations 21 so positioned relatively to the lever as to engage the lever and lock it in any desired adjusted position. There is enough give to the lever to allow its movement past the teeth. The runners give sufficient supporting sur face to carry the hone in soft ground. Tn this respect it is very much more desirable than a wheel. Tt will be noted that the runners are arranged practically in the centers of the sections and between the front and rear rails so that the sections are practically balanced on the runners. Tn this way it is possible to arrange the runners between the rails and in a convenient position to be operated.

By forming the frame with the front and rear rails formed of angle iron, the vertical portion extending downwardly and the horizontal portion on top and the connecting barsof angle iron, the horizontal'portion on the bottom and resting on the horizontal portion of the rails, the vertical portion exmg the connecting bars in the line of the draft these bars may be made much lighter than where otherwise arranged because when the rear rails strike a pronounced obstruction, the strain is largely a tensile one on these" connecting bars which they can readilysustain especially as the vertical web of the angle iron forming the connecting'bars receive directly any deflecting strain due to the offsetting of the point of strain on the rear rail. One of the principal objects of this invention is to form a comparatively light road hone and one that can be readily the rear rails overlapping the 30 each part arranged between the front and 3 rear rails and adapted to lift said rails from cutting position; and means for adjusting said runners relatively to the frame.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
